For longer-term effects, extending rehabilitation into domiciliary care settings may be necessary. There are few studies evaluating precisely this modality of management in a home setting. This review analyses the current literature on home based rehabilitation. The benefits of pulmonary rehabilitation, the practical aspects of its application, and its advantages and limitations are detailed. The few data on economic aspects of home rehabilitation are also discussed. Home-based pulmonary rehabilitation is effective with positive short-term effects on quality of life, breathlessness and effort tolerance. Its practical application needs to be defined. Home-based pulmonary rehabilitation appears to be an effective intervention in patients with COPD but more studies are necessary to evaluate it fully.

Four different forms of the protein were genetically engineered, purified, and studied: CelGL (the entire form of CelG), CelGcat1 (the catalytic domain of CelG alone), CelGcat2 (CelGcat1 plus 91 amino acids at the beginning of the cellulose binding domain [CBD]), and GST-CBD(CelG) (the CBD of CelG fused to glutathione S-transferase). The biochemical properties of CelG were compared with those of CelA, an endoglucanase from C. cellulolyticum which was previously studied. CelG, like CelA, was found to have an endo cutting mode of activity on carboxymethyl cellulose (CMC) but exhibited greater activity on crystalline substrates (bacterial microcrystalline cellulose and Avicel) than CelA. As observed with CelA, the presence of the nonhydrolytic miniscaffolding protein (miniCipC1) enhanced the activity of CelG on phosphoric acid swollen cellulose (PASC), but t...

Conclusion Home-based pulmonary rehabilitation appears to be an effective intervention in patients with COPD but more studies are necessary to evaluate it fully.

A graph is strongly rigid if the clone PolE is the clone of projections. It is projective if the only idempotent operations in PolE are projections. We show that a graph is projective if and only if the idempotent binary operations in PolE are conservative. Other criteria are given for finite graphs. These results are used to construct large families of strongly rigid graphs. The smallest strongly rigid graph is described.

The result follows from an analysis of NU polymorphisms of strongly bipartite digraphs, i. e., whose vertices are either a source or a sink. We show that the retraction problem for a strongly bipartite digraph H has finite duality if and only if H admits an NU polymorphism. This result allows the use of tree duals to generate the variety of digraphs admitting a k-NU polymorphism.

We further delineate a very simple subset that generates the variety of j-absolute retracts; in particular we show that the class of reflexive graphs with a 4-NU operation coincides with the class of 3-absolute retracts. Our results generalize and encompass several results on NU-graphs and absolute retracts.
